CAMERA.

s PEoIF'IcA'rIoN forming part of Letters Patent No. 72 dated April 1903- Application filed July 15, 1902.

To (all whom, it may concern:

Be it known that I, MARTIN SoHuLL, a citi zen of the United States, residing at Rochester, in thecounty of Monroe and State of New York,have invented new and useful Improvements in Cameras, of which the following is a specification.

This invention relates to improvements in cameras, and has especial relation to that type of camera in which the bed for supporting the camera-front in projected position is formed by the front of the inclosing case and is provided with guides for the travel and retention of the camera-front when the bed is swung into supporting position.

One object of the invention is to provide a camera of the above character, though not necessarily such,with a bed capable of lateral adjustment with relation to the camera-case,-

and especially to secure this relative lateral adjustment in addition to the vertical relative adjustment of these I parts, so that by virtue of the combined adjustments the camera-front may be readily and conveniently directed to any point within a given circle of movement without the necessity of changing the position of the tripod.

The invention contemplates the attachment of the tripod to either the case or the bed,

but preferably the case receives the tripod and is made the fixed member, as by such an arrangement of the parts the photographic plate is readily brought into the proper picture-planeand undisturbed by subsequent adjustments of the camera.

Another object of the invention is to provide means for supporting the bed at different inclinations by having an adjustable connection between the bed and case for the purpose, which will admit of the bed be.- ing swung to close the front of the case without requiring detachment of said means and which will be disposed in compact form within the case when said case is closed.

Another object is to provide for the independent adjustment of the bed-supporting means, whereby to admit of the lateral adj ustment of the bed with relation to the case.

Another object is to provide the camerafront with automatic means for looking it in projected or other position upon the guides and also bring about the release of the said Serial No. 115,730: N m -l locking means and relieve it of engagement with the guides during the operation of moving the front upon the bed.

In the accompanying drawings, Figure 1 is a perspective view of a camera constructed in accordance with this invention, showing the camera-front projected. Fig. 2 is a top view ofthe camera in projected position. Fig. 3 is a top view in which the camera-bed is shown in a laterally-adjusted position, the camera-front and a part of the case being shown in horizontal section to disclose the locking means of the front and the construction by which the lateral adjustment of the bed is effected. Fig. 4 is a view in front elevation fromwhich the camera-front has been eliminated by a section taken on line 1) '0 of Fig. 2. Fig. 5 is a side view of the camera in which the bed is shown butpartly swung away from the case, the bed and a portion of the case being shown by a section taken on the line m to of Fig. 2. Fig. 6 is a transverse section View taken on the line y'y of Fig. 3, and showing only the lower portion of the camera-front. Fig. 7 is an enlarged detail view of a'portion of the bed and one of the supports therefor. I

Referring to the drawings, 1 indicates a shallow case of the character employed in the type of camera heretofore mentioned, inwhich said case for-ms the back of the cameraand also receives and incloses the bellows 2 when collapsed and the camera-front 3, and4 indicates the front of'said case, which also constitutes a camera-bed, being provided with the usual runways or guides 5 for thecamerafront. i

To provide for the relative lateral movement of the bed 4 and also preserve the usual vertical movement thereof, this bed is hinged toa member 6, which is pivoted at 7 to the bottom of the case, adjacent the front edge thereof. This pivoted member consists, preferably, of a strip of metal formed after the manner of a hinge, the bed being formed or provided with a connecting edge to cooperate with the said strip, so that thebed and stripv will be held pivotally together by a hinge-pin 8. The bottom of the case is suitably recessed on its under side to receive the pivoted plate 6 and admit of an oscillating movement thereof within necessary limits, and over this recessed portion is secured, so as to lie flush with the bottom of the case, a metal plate 9, which furnishes a durable mounting for the pivot 7 and a bearing for the plate 6 in its oscillating movement, while at the same time increasing the security of the support to said plate and holding it secure against movement in the direction of the hinge movement of the bed. A small plate 10 is located on the inner surface of the bottom of the case to receive the upper end of the pivot 7 and provide a durable support therefor. I

In order to secure the pivoted plate 6 in its various adjustments, there is formed on one side thereof an upwardly-projecting arm 11, which extends into the case adjacent one of its sides through a slot 12, formed in the bottom of the case, of such length as to admit of the oscillating movement of the plate 6, and upon this arm there projects outwardly through a slot 13, formed in the side of the case, a screw-threaded extension 14, which receives a locking-nut 15 for binding the arm 11 to the side of the case, thereby securing the plate 6 in adjusted position. To receive the wear of these locking parts and the better secure the movement of the plate 6 upon slight turning of the nut to make the plate free for movement, there is provided a concave slotted'plate 16, Fig. 3, on the inside of the case over the slot or opening 13, the curve of the concave surface of the plate conforming to the are described by the arm 11 in its movement, so that but little movement of the nut will be required to draw the arm into binding contact therewith at any point. This nut may bear upon the opposite side of the plate 16 or a separate outer plate (not shown) may be provided for this purpose. As will be seen, a depression 17 is provided, so as to bring the binding-nut within the lines of the case.

The bed at is maintained in its vertical adjustments by the supports 18. These comprise each a main swinging member 19, pivoted to the case at 20, and a shorter member 21, pivoted to the main member at 22 and forming a link connection between it and the bed, which latter member when the bed is raised to close the case will fold upon the swinging member, as shown in Fig. 5. To limit the pivotal movement of the link member when said member becomes straight with the main member, either when extended or folded, said link member is provided with a stop 23, formed by an inturned projection on the end of said link member, which extends into a semicircular slot23, formed about the pivot-aperture and on the main member.

To advance the supports 18 and thereby force the bed outward from its folded or closed position uponits releasing from the depressible latch shown, each support is provided with aspring 24, which is secured to the sides of the case adjacent the support, and has its arm held in sliding engagement with the support by extending through a perforation formed in a bend or offset 19 of the support. The pressure of these springs is sufficient to force the bed into the position shown in Fig. 5 and from which it can be readily lowered.

The pivot 25, by which the link member 21 is connected with the bed, is mounted to slide back and forth on the bed for the purpose of the vertical adjustments of the bed, and also to adapt the supports 18 to a change of position independent of each other to accommodate at the same time the lateral adjustment of the bed, as shown by Fig. 3. cut instance this sliding connection is attained by providing two parallel guides, which, as shown, are preferably formed by an inwardly-projecting flange 26, formed about the edge of the bed and the outer upstanding part of the adjacent guide 5, the said flange and said guide being provided with oppositely-disposed parallel slots 27 and 28, respectively, through which the sliding pivot 29 extends and forms and operates after the manner of a cross-head, the link member extending between the said guide members. This sliding pivot is provided with a bearing-head 30'on its inner end and is screwthreaded on its outer end to receive a nut 31, by which it may be secured to the guides in adjusted position.

Between the guides in which the pivot 29 has movement is located a spring 32, secured to the bed at 33 and adapted to bear upwardly at all times on the pivot for the purpose of furnishing a yielding bearing therefor, whichwill compensate for any wear of the parts and produce at all times a certain amount of friction, yet admit of the greatestfreedom of movement of the sliding pivot. This spring is formed with a central slot 34, which receives the end of the support member 21 and serves to maintain the support in position centrally of the guides. A notch 35 to receive the pivot 29 is formed in the spring at a point at which the support will rest when the bed is in a horizontal position or when closed, so that a stop is thus provided whereby to facilitate bringing the pivot into its normal position in the guide and to hold it against accidental sliding from such position.

The guides or ways 0 forthe camera-front employed in the presentinvention are twoin nu mber,each comprisin g a rectangular trough having on the inner side of its vertical portion and adjacent the upper edge thereof a groove 5, which receives and retains the side edge of the sliding foot portion 3 of the front, two such sliding portions being employed in the present instance. Adjacent the said foot portion and on each side thereof the front is provided with an oifset or shoulder 3, which is adapted to overhang the upper edge of the guide and assist the guiding function thereof, Fig. 6.

The inner rails of the guide are each provided with a notch 5 Fig. 5, near the forward ends and opposite each other, for the purpose of receiving the bar 36, by which the In the pres TIC front may be locked against movementin its projected position. This bar rests upon the inner rail and is provided with a forwardlyprojecting tongue 37, which being fulcrumed on the cross-bar 38 forms a lever for lifting the bar from engagement with the guides and at the same time forms a finger-hold for projecting or retracting the front. A pin 38 loosely secures the tongue to the cross-bar of the front, and a flat spring 39 is secured to the cross-bar, so as to bear upon the tongue 37 at a point in the rear of its fulcrum and normally hold the bar 36 in contact with the guide. In the operation of pulling out or pushing in the front a slight downward pressure on the tongue lifts the bar 36 free from the guide, while its release at any point assists by its contact with the guide to apply a friction to prevent the front from sliding too freely or becoming loose within the guide as by wearing of the parts.
